A high-end doll balances realism with durable engineering. The external layer is typically a skin-like material that can be silicone or a premium thermoplastic elastomer, chosen for its texture, translucence, and resilience. Beneath this skin lies a multi-structure frame that enables poseability: an internal skeleton or joint system made of metal or strong polymers supports articulation of the neck, shoulders, elbows, hips, knees, and wrists. This frame is often connected to the torso with flexible joints to allow natural movement.

Within the torso, some dolls feature a lightweight core or internal cavity that improves balance and stability during posing. The head usually contains a socket for eyes and a neck joint that provides a range of motion for head turns and tilts. Hair is attached at the scalp and may be rooted or set into a detachable wig. Some models offer optional features such as temperature control or sensors to enhance realism, but these vary by design. Overall, the build focuses on safe materials, precise joints, and a convincing surface texture that mimics realistic skin.
